Hey,

Thanks for this detail. Unfortunately there are lot of differences between various implementations of tools. May be manageable for commands like paste or head, but too many for tools like grep or sed or awk and so on. See this stackoverflow thread for an example for sed differences.

To cover this, there's a note in README that says:

Examples have been tested on GNU/Linux - there'd be syntax/feature variations with other distributions, consult their respective man pages for details.

and each command also includes details like version number, few lines from man page, etc to indicate which implementation is being presented.

I'm no longer actively working on this repo.
